Korvac vs high evolutionary vs the stranger

Poll Results

Korvac, the High Evolutionary, and the Stranger, all "people" who are regularly described as having "Galactus-level power," get into an argument over which one is the most powerful sub-Celestial, non-conceptual, non-magical, non-sentient cosmic cube (have I left out any other qualifiers that leaves us with only this group of 3?) entity out there. Their tempers get the better of them and they start a fight on the dwarf planet Eris.

Who wins, and who comes in second? Win by any means. No prep, no minions, no extra tech beyond the High Evolutionary's armor. Each is at their most powerful.
